I wonder if the old worm catching method of 2 metal rods in the ground hooked up to an electrical plug would work. Then if they did surface from the "charge" you could do some golf practice with a moving target/ball.

probably isnt legal and now or when we did it when i was kid,,, we would drop carbide in the holes and after it started hissing we would step back about 10 feet and thump lit matches over the holes,,,,,, nothing like fire works under ground,,,,,, keep n mind i was a kid in the 60's

I saw this on TV and it really works too. Sneak some speakers into the neighbors yard across the street. Then depending on the moon phase play Bach, or Simon & Garfunkel. They'll all leave your yard for the neighbor's yard.

+ 1! We did this same thing, but in the early 90's! We weren't smart enough to actually thump the matches. We just stood over the hole, lit the match, and accepted the singed eyebrows as a cost of the fun.
